Headlight lens for a motor vehicle headlight
First Claim
1. A headlight lens for a vehicle headlight having a light source, the headlight lens including:
- a lens body made of a transparent material, which includes a surface to face the light source and a surface to face away from the light source; and
an emblem, situated on the surface to face the light source, having a basal surface, which, with respect to the surface to face the light source or with respect to an optical axis of the headlight lens, is sloped in such a way that light entering into the lens body through the surface to face away from the light source parallel to the optical axis of the headlight lens is subject to a total reflection at the basal surface.

Abstract
The present invention relates to a headlight lens for a vehicle headlight having a light source, in particular for a motor vehicle headlight, as well as a vehicle headlight, in particular a motor vehicle headlight, having a light source and a headlight lens. The headlight lens including a lens body is made of a transparent material, which includes a surface to face the light source and a surface to face away from the light source. The headlight lens having an emblem, on the surface to face the light source, having a basal surface, which, with respect to the surface to face the light source or with respect to an optical axis of the headlight lens, is sloped in such a way that light entering into the lens body through the surface to face away from the light source parallel to the optical axis of the headlight lens is subject to a total reflection at the basal surface.
